[Obliterous]

Is it possible to add text overlay & timestamp to image/video so that multiple similar streams can be distinguished?

This functionality is not there. Need to add it.

It should be quite simple using opencv.The documentation for the specific function you need to use can be found here:

Some example code:

putText( image2, "OpenCV forever!", org, FONT_HERSHEY_COMPLEX, 3,Scalar(i, i, 255), 5,lineType );

It is taken from here:

Windows version already has this feature:

No OpenCV needed.
